Member Function Documentation
| virtual int log4tango::Appender::_append | ( | const LoggingEvent & | event | ) | [protected, pure virtual] |
Log in Appender specific way.
Subclasses of Appender should implement this method to perform actual logging.
- Parameters:
-
event The LoggingEvent to log.
Implemented in log4tango::FileAppender, log4tango::OstreamAppender, and log4tango::RollingFileAppender.
| int log4tango::Appender::append | ( | const LoggingEvent & | event | ) | [inline] |
Log in Appender specific way.
Returns -1 on error, 0 otherwise.
- Parameters:
-
event The LoggingEvent to log.
| virtual void log4tango::Appender::close | ( | void | ) | [pure virtual] |
Release any resources allocated within the appender such as file handles, network connections, etc.
Implemented in log4tango::FileAppender, and log4tango::OstreamAppender.
| const std::string& log4tango::Appender::get_name | ( | void | ) | const [inline] |
Returns this appender name.
| bool log4tango::Appender::is_valid | ( | void | ) | const [virtual] |
Check if the appender is valid (for instance the underlying connection is ok) This default implementation always return true.
Overload to define your own behaviour.
- Returns:
- true if the appender is valid, false otherwise.
Reimplemented in log4tango::FileAppender.
| void log4tango::Appender::level_changed | ( | Level::Value | new_level | ) | [protected, virtual] |
Inform an appender that its Logger's logging level has changed.
The default implementation does nothing.
- Parameters:
-
new_level The new Logger's level.
| bool log4tango::Appender::reopen | ( | void | ) | [virtual] |
Reopens the output destination of this Appender, e.g.
the logfile or TCP socket.
- Returns:
- false if an error occured during reopening, true otherwise.
Reimplemented in log4tango::FileAppender, and log4tango::OstreamAppender.
| virtual bool log4tango::Appender::requires_layout | ( | void | ) | const [pure virtual] |
Check if the appender uses a layout.
- Returns:
- true if the appender implementation requires a layout.
Implemented in log4tango::LayoutAppender.
| virtual void log4tango::Appender::set_layout | ( | Layout * | layout = 0 | ) | [pure virtual] |
Change the layout.
Implemented in log4tango::LayoutAppender.
